' yarn takes place adjacent the eyes of the wires and prevents twisting between the flyer wires and the takeoff bobbin.

' A further object is to provide a novel'and eflicient flyer construction which aflords a ready adjustment or change of relative angularity of the fiyer wires to control the tension required for twisting the various sizes of yarn.

p A still further object of the invention is the provision of a simple and inexpensive means for efiectually anchoring the flyer wires to the holder.

In the accompanying drawing Figure 1 is a fragmentary front View of a portion of a spinning machine showing my improved fiyer applied thereto. Figure 2 is an enlarged sectional side View of the fiyer mounted on the bobbin-spindle, the wires being shown by full lines in their relative operative position while running and by dotted lines in their inoperative or state of rest positions. Figure 3 is a top plan view thereof corresponding to the full line position of the parts shown in Figure'2. Figure 4 is an enlarged top plan view of the holder for the flyer wires, the parts being in their partially assembled positions. Figures 5 and 6 are perspective views of the complementary holder plates or members.

Similar characters of reference indicate corresponding parts throughout the several views. 7

This invention is applicable to spinning machines of any suitable and Well known construction, 10 indicating a bobbin-spindle and 11a takeofi bobbin mounted thereon. The'thread or yarn from each bobbin extends upwardly through the eyes of a double setof flyer wires 12 and 13 mounted on a holder or fiyer-block applied to the bobbinspindle and indicated generally by the numeral 14, and thence upwardly through'a guide or centering eye 15 to a-driven take-up spool (not shown). f

' While the fiyer-block, which is revolvably mounted on-the spindle 10, may be o1 any appropriate construction, it is preferably in the form of a self-contained unit consisting of an anchoring sleeve orjournal 16 adapted for frictional engagement with the'tapered end of the spindle, a hollow bearing member 17 loosely fitted on the sleeve to revolve thereon, and abase member or spider applied to the bearing member and to which the flyer wires 12, 13 are detachably connected. ,As shown in Figures 1, 5 and 6 this wire-attaching spider preferably consists of superposed plates Band 19 having registering central openings 20,21, the lower plate 18 having an annular flange 22'about its opening which is rolled over the edge of the companion plate-opening to hold the plates together but permit of their relative movement about the axis of such openings. The spider may be held to the bearing member 17 bya pressed fit in the manner shown in Figure 2.

The flyer wires 12, 13 terminate at their outer ends in eyes 23, 24, respectively, while their inner ends have angular attaching portions 25 which engage correspondingly shaped retaininggrooves' 26 in the opposite upper sides of the lower spider-plate 18 and are clamped in place'by' the shiftable top plate 19. Said plate 18 is provided along its side edges with inwardly-bent flanges 27 which form arcuate grooves 28 for receiving the corresponding marginal edges of the upper plate in the manner shown in Figure 4. These flanges are notched at 29 in line with the wire-anchoring grooves 26 and the opposite edges of these notches constitute shoulders against which the shanks of the fiyer wires bear to resist their lateral displacement, In mounting the wires, the upper plate 19 is turned to the position shown in Figure 4;, after which the wires are inserted in the exposed grooves 26 with their angular portions 25 disposed side by side therein and the upper plate turned to its clamping position shown in Figure 3. By this construction and arrangement of parts the flyer wires are reliably held against displacement and they may be readily replaced when desired in a minimum period of time.

Heretofore, the disposition of the flyer wires has been such that the path of the yarn between the centering eye and the takeoff bobbin 11 was in a substantially direct or slightly curved line, the curve being caused by the centrifugal force acting with the air resistance. In making the higher twisted yarns, especially by single operation, this curve and the slight angularity of the yarn in passing through the eyes of the flyer wires have resisted the torsional force but have not arrested it, therefore resulting in the actual twisting of the yarn at the point where it leaves the take-off bobbin and where the torsional force is greatest. This force is constant and spends its energy against the resistance of the turns or coils of yarn about the bobbin, and results in the adjoining or contacting yarn-turns being often twisted together and causes not only breakage of the yarn but the production of inferior and defective yarn.

In my arrangement of the flyer wires presently to be described, I eliminate the objections above set forth by preventing the twist ing of the yarn below or between the wires and the take-off bobbin and also control the tension required for twisting various sizes of yarn. To this end, I preferably arrange each set of fiyer wires 12, 13 in the angular spread formation shown in Figure 3, the wire 12 being straight and shorter than the companion wire 13 and having its eye substantially vertical. The longer wire 13 terminates in a depending arm and its eye is disposed substantially horizontal or at right angles to the eye of the companion wire 12.

When the parts are at rest, the wire 13 assumes the position shown by dotted lines in Figure 2, but when in motion and operative, it assumes the full line position shown in said figure, such position resulting from the centrifugal force created by the revolving flyer. In this operative position of the parts, it will be noted that the eyes 23, 24 of the respective wires 12, 13, are so disposed that thepath of the yarn travel as it passes through these eyes is diverted out of a direct line to approximately right angles to the stretches of yarn leading to and from the eyes, which angle or offset affords an efl'ective means of arresting the torsional force and twisting of the yarn at the eyes of the wires. and thus prevent twisting of the yarn between the fiyer wires and the take-0H bobbin. This angular path of the yarn may be readily changed line to an angular one at the point of the eyes of the flyer wires also serves to increase the tension on the yarn and by clamping the angularity at this point in the manner above described, the tension may be changed accordingly. Such a change of tension is necessary to control the twisting of the various sizes of yarn. By regulating the length of the straight wire 12, which is the means of changing the degree of the angle of the yarn travel, it will be understood that both the twisting and the tension on the yarn are controlled by the fiyer when in operation.

It willbe observed from Figures 2 and 3, in the operative position of the parts that the wire-eyes 23, 24 are at substantially the same elevation but at radially and circumferenplates having a retaining groove adjacent its outer edge for receiving the inner end of a flyer-wire and an inwardly facing guide-way along its marginal edge intersecting said groove, and the other plate being revolvable over the companion plate to cover and uncov er its groove and having its marginal edge engaging said guide-way.

2. A flyer, comprising a body including superposed, relatively movable plates, one of said plates having an angular-shaped retain-" ing groove adjacent its outer edges for receiving the inner end of a fiyer-wire and an inwardly-bent flange along its marginal edge forming a guide-way, the other plate having its marginal edge engaging said guide-way and revolvable over the companion plate to cover and uncover its groove, said flange having a notch therein registering with the wireretaining groove.

3. A flyer, comprising a body including a pair of superposed plates guided for relative turning movement one over the other in interlocking relation, one of said plates having a wire-retaining groove of angular shape extending inwardly from its outer edge and facing the companion plate, the latter being adapted to overlie said groove in frictional clamping engagement with the wire, and means applied to said groovedvplate for receiving the marginal edges of the companion plate to hold the same in'its clamped position. i. A flyer, comprising a body including a pair of superposed plates guided for relative turning movement one over the other in inter locking relation, one of said plates having a tances from the body-axis to divertthe normal path of travel of the thread between its takeoff and take-up points in both radial and circumferential directions relative to the flyer.

6. A flyer for spinning machines and the like, comprising a body, and a pair of flyerwires disposed at an acute angle to each other and radiating from said body with their shanks in substantially the same plane and having thread-engaging eyes thereon, said eyes being radially spaced beyond the flanged head of the bobbin and being at substantially the same elevation during the operation of the machine, whereby the thread at the junction of said eyes is directed in a path of travel at approximately right angles to its leading and trailing ends.

7. A flyer, comprising a body, and flyer wires applied thereto in pairs atoppositesides of the body-axis,each pair diverging outwardly therefrom having their shanks in substantially the same plane and being of relatively different lengths and terminating at their outer ends in thread-engaging eyes, the eyes of each pair of wires being arranged at different radial distances from the flyer axis.

8. A flyer, comprising a body, flyer wires applied thereto in adjoining acute, angular relation on opposite sides of the flyer-axis with their attaching shanks disposed radially in substantially the same horizontal plane, one of said wires terminating at the outer end in a depending arm free to flex outwardly and upwardly, and thread-engaging eyes formed at the free ends of said wires, said depending arm being adapted to flex outwardly and upwardly during the rotation of the flyer to bring its thread-engaging eye outwardly of and substantially horizontally in line with the eye on the companion wire to direct the thread at approximately right angles to its normal path of travel.

9. A flyer, comprising a body including superposed plates guided for relative turning movement one over the other in interlocking relation, one of said plates having wireretaining grooves extending inwardly from its outer edges and facing the companion plate, and pairs of flyer wires applied to dia metrically opposite sides of the body-axis, the wires of each pair having their shanks arranged at an acute angle to each other and having their attaching inner ends seated in said plate groove, said Wires having threadengaging eyes at their outer ends arranged at different radial distances from the bodyaxis.
